Some dinners just feel like cheating — in the best way. You’re barely doing anything, the pan is doing all the work, and twenty minutes later you’re sitting down to a bowl of pasta that looks like it came from somewhere with a wine list. That’s this one. Sweet crab folded into a creamy, garlicky sauce with fresh tomatoes and a squeeze of lemon, tossed with bucatini. It’s the kind of meal that makes a Tuesday feel worth it.
Ready in about 30 minutes. No fuss.

Why This One’s Worth Making
The sauce has some actual thought behind it. Garlic goes in first, then chopped tomatoes, Italian seasoning, Dijon mustard, lemon juice and zest — all of that simmers together before the cream even goes in. By the time the cream joins the party, the tomatoes have mostly dissolved and the whole thing has this slightly sweet, slightly tangy base that plain cream pasta just doesn’t have.
Then the crab goes in and it really comes together. Little sweet bits of it throughout every forkful. It doesn’t compete with the sauce — it belongs in it.
What You’ll Need

- Bucatini — thick, hollow noodles that hold onto cream sauce better than thinner pasta. Sub linguine or spaghetti if that’s what’s in the cupboard.
- Butter — just one tablespoon to start the sauce.
- Garlic — three cloves. Don’t go light on it.
- Fresh tomatoes — two medium ones, roughly chopped. They cook down almost completely, which is the point.
- Italian seasoning — the herby backbone of the sauce.
- Lemon juice and zest — half a lemon. The zest makes a bigger difference than you’d expect.
- Dijon mustard — one tablespoon. Sounds odd, tastes right. Don’t skip it.
- Heavy cream — the sauce base. This is not the recipe to go light on.
- Cornstarch — a small amount mixed with cold water keeps the sauce from going watery.
- Crab meat — about 8 ounces, cooked. More on options below.
- Parmesan — grate it yourself. The pre-shredded stuff has fillers that make the sauce grainy.
- Fresh parsley — just a bit at the end.
A Few Things That Help
Fresh-grated parmesan really does matter here — the block-to-grater kind melts into the sauce cleanly. The powdery stuff in the green can will clump.
Keep the heat low once the cream is in. A hard boil can break the sauce and you’ll end up with something grainy instead of silky. Gentle simmer only.
And save some pasta water before you drain. A splash of it is the easiest fix if the sauce tightens up too much once the pasta goes in.
How to Make It
Salt your pasta water well and get it going first. The sauce comes together fast, so the timing works out if you start the water before anything else.
Melt the butter in a skillet over medium heat, then add the garlic. Let it go for about a minute — you want it soft and fragrant, not browned.
Add the chopped tomatoes, Italian seasoning, lemon juice and zest, and Dijon mustard. Stir it all together and pour in the cream. Let it simmer for about 5 minutes, stirring occasionally. The tomatoes will start to break down and go soft — that’s exactly what you want. They’re essentially dissolving into the sauce.

Stir the cornstarch into a teaspoon of cold water until smooth, then add that to the skillet. This is what thickens everything up just enough so it coats the pasta instead of sliding off it.
Add the crab and parmesan. Stir gently. Give it a couple of minutes until the crab is warmed through and the sauce has tightened up. Taste it and add salt and pepper now.
Drain the pasta, saving a mug of the cooking water. Add the pasta straight into the skillet and toss until it’s coated. If it feels thick, a splash of pasta water fixes that. Parsley and extra parmesan on top, then it’s done.
That’s dinner.
Which Crab to Use
Fresh Dungeness crab is the best version of this, full stop. Sweet, clean flavor, and if you can find it at a fishmonger or in the refrigerated section of a good grocery store it’s worth it.
Canned crab is a solid backup. Drain it well. The flavor is a little muted compared to fresh but the sauce is strong enough that it still works.
Imitation crab is fine if that’s what the budget allows. It won’t taste the same but it’ll taste good.
Anywhere around 8 ounces is the target. Honestly a bit more doesn’t hurt.

Serving
Long pasta is the move — bucatini, linguine, spaghetti, fettuccine. The sauce is creamy enough that it needs something substantial to cling to.
Crusty bread on the side is basically mandatory for sauce scooping. A simple green salad if you want something fresh alongside it. A lemon wedge at the table for anyone who wants more brightness.
Leftovers
Two days in the fridge, in a sealed container. Reheat low and slow on the stove with a splash of water or cream. It’s fine the next day but it’s best when it’s fresh, so plan accordingly.

kcalTender bucatini tossed in a garlicky cream sauce with fresh tomatoes, lemon, and sweet crab meat — a weeknight dinner that feels anything but ordinary.
Ingredients
8 oz uncooked bucatini (or pasta of your choice)
1 tbsp butter
3 garlic cloves, minced
2 medium tomatoes, roughly chopped
½ tsp Italian seasoning
Juice and zest of ½ lemon (roughly 1 tbsp juice)
1 tsp Dijon mustard
1 cup heavy whipping cream
½ tsp cornstarch
8 oz cooked crab meat (see Notes)
½ cup freshly grated parmesan, plus more for serving
Salt and pepper, to taste
½ tbsp fresh parsley, chopped (or to taste)
Directions
- Bring a large pot of well-salted water to a boil. Cook the bucatini al dente following the package directions. Before draining, scoop out a cup of pasta water and set it aside.
- While the pasta cooks, melt the butter in a skillet over medium heat. Add the garlic and cook for about 1 minute, stirring, until fragrant and just softened.
- Add the tomatoes, Italian seasoning, lemon juice, lemon zest, Dijon mustard, and cream. Stir to combine, then let the sauce simmer for about 5 minutes until the tomatoes begin to break down and soften into the sauce.
- In a small bowl, dissolve the cornstarch in 1 teaspoon of cold water. Pour the mixture into the skillet and stir it through.
- Add the crab meat and parmesan. Cook for 2–3 minutes, stirring gently, until the crab is heated through and the sauce has thickened slightly.
- If the sauce thickens too much at any point, stir in a splash of the reserved pasta water to loosen it back up.
- Drain the pasta and add it directly to the skillet. Toss until everything is well coated. Taste and season with salt and pepper. Top with chopped parsley and extra parmesan, and serve right away.
Notes
- Crab options: Fresh cooked Dungeness crab is the best choice when you can find it — look for ready-to-eat crab meat in 8 oz containers in the refrigerated seafood section of most grocery stores. Canned crab works well too; just drain it thoroughly first. Imitation crab is a budget-friendly swap that still tastes good in this sauce. Anything close to 8 oz is fine, and a little extra never hurts.
- Pasta: Bucatini is the top pick here, but linguine, spaghetti, or fettuccine all work just as well.
- Parmesan tip: Grate it fresh from a block — pre-shredded parmesan has anti-caking agents that can make the sauce grainy rather than smooth.
- Storage: Keep leftovers in a sealed container in the fridge for up to 2 days. Reheat gently on the stove with a small splash of water or cream to bring the sauce back together. Best eaten fresh.
